Seeing in dim light and the dark is governed by different things than your lenses. It could be that your body has a problem producing the rhodopsin it needs for your rods to function in low light levels, which would have nothing to do with the shape of your lenses at all... and that's not something your body can store up, because light destroys it on contact (that's why when you're in a bright room and turn off the light, you just see that odd little orangish light haze, but gradually start seeing well in the dark... because your eyes have none of the chemicals they need to see the instant the light is turned off because the light's been busy destroying it until that moment, and need some time to build up enough of the chemical to let you see without so much light).
For instance, I have very lovely blue eyes that optometrists love to see because I'm that one in a million or so person who has absolutely no pigment in my eyes anywhere (before anyone says it, I'm perfectly aware most people with this condition end up with purplish eyes... but I'm assured by many doctors it's possible for them to be blue, as well). The good news is they can drag in students and show them in real life what every structure of the eye looks like. The bad news is they have to shine a very bright light in my eyes and keep idly making comments like "and because he has no pigmentation in his eyes and you can transparently see all the structures in his eyes, they let in far too much light to be comfortable in the daytime, so the light we have shining in there must be positively excruciating to him".
So, I have amazing night vision, but I can't stand being out and about in the daytime because everything starts to wash out and take on that sort of "light at the end of the tunnel" look to me. It's very hard for me to see in the daytime.
It has nothing to do with the lenses in my eyes, though. Those are incredibly consistent and take YEARS to change shape, not minutes... it's the other structures which are causing my, and probably your, specific problems.

no..it(power) may slowly increase..over months or yrs...but it doesnt fluctuate. ur problem abt seein in the dark may be due 2 accomodation....get urself checked again...also if possible do an indirect ophthalmoscopy to check ur retinal condition

a chance in inter ocular pressure could cause a small change the the shape of the eye causing a mild change. the IOP change could be associated with glaucoma
